PPG introduces ultra-neutral, light-gray OPTIGRAY glass

New light-gray hue delivers a warm, neutral aesthetic for low-e and uncoated glass

PPG Industries (NYSE:PPG) has introduced OPTIGRAY® glass, an ultra-neutral, warm-light-gray glass designed to maximize light transmittance and clarity, and to work with SOLARBAN® coated, solar control, low-emissivity (low-e) glasses to enhance solar control performance. SOLARBAN 60 OPTIGRAY glass (left) is significantly lighter and more neutral than SOLARBAN 60 SOLARGRAY® glass by PPG, as shown here.

SOLARBAN® 60 OPTIGRAY® glass (left) and SOLARBAN z50 glass are part of PPG Industries’ (NYSE:PPG) family of high-performing, neutral-coated, low-emissivity (low-e) glasses. SOLARBAN 60 OPTIGRAY glass gives architects the option of an ultra-neutral, warm-light-gray appearance while SOLARBAN z50 glass has a cool-gray hue with a slightly blue tint, as shown.

OPTIGRAY glass is significantly lighter and more transparent than SOLARGRAY® glass, as shown here. The light-gray tint in OPTIGRAY glass eliminates the green naturally present in conventional clear glass formulations, producing a highly-transparent, super-neutral aesthetic that can actually show less color than clear glass.

PITTSBURGH, June 17, 2014 – PPG Industries (NYSE:PPG) has introduced OPTIGRAY® glass, an ultra-neutral, warm-light-gray glass designed to maximize light transmittance and clarity, and to work with SOLARBAN® coated, solar control, low-emissivity (low-e) glasses to enhance solar control performance.

Glenn T. Miner, PPG director of construction, flat glass, said Optigray glass is formulated to offer an extremely light-gray tint that eliminates the green naturally present in conventional clear glass formulations. The result, he adds, is “a highly transparent, super-neutral aesthetic that can actually show less color than clear glass.”

To optimize performance, Optigray glass is designed to function as a substrate for solar control, low-e coatings such as those on Solarban 60, Solarban 70XL, Solarban 67 and Solarban R100 glasses. In a standard 1-inch insulating glass unit (IGU), Solarban 60 Optigray glass has visible light transmittance (VLT) of 50 percent and a solar heat gain coefficient (SHGC) of 0.30, which yields a light-to-solar-gain (LSG) ratio of 1.67.

With Solarban 70XL glass in the same configuration, Optigray glass generates an LSG ratio of 1.99 based on VLT of 47 percent and a SHGC of 0.24.

As part of PPG’s wide range of tinted float glasses, Optigray glass features an appearance that is considerably lighter and more subtle than that of SOLARGRAY® (light-gray) and GRAYLITE® II (rich dark-gray) glasses. Other tinted glasses from PPG are SOLARBRONZE®, SOLARBLUE®, PACIFICA®, ATLANTICA®, AZURIA® and SOLEXIA® glasses.
